Something more fundamental than a shift in tactics is underway. 

The mechanics that once defined B2B go-to-market, linear journeys, channel-driven engagement, and neatly separated functions are being overtaken by a far less predictable reality. Buyers now move fluidly, informed and often ahead of the organisations trying to reach them. 

In this environment, optimisation is no longer enough; the model itself is under strain. What’s emerging is not an evolution, but a breaking point—one that demands a rethinking of how growth is designed, executed, and sustained.

Forrester’s latest research, The GTM Singularity Is Here, unveiled at B2B Summit North America, captures this inflexion point. It calls on B2B leaders across marketing, sales, customer success, and product functions to move beyond legacy GTM practices and adopt an ARC (augmented, resilient, and collaborative) approach that aligns with today’s AI-enabled buyer. 

Despite years of volatility driven by changing buyer behaviour and unprecedented information access, B2B firms have failed to change how they engage with buyers — clinging to ineffective marketing practices such as impersonal mass emailing, marketing-qualified lead obsession, gated content, and siloed teams. 

AI is quickly making these practices untenable as it transforms buyer journeys and hands even more power to buyers.

“The GTM singularity is a reckoning for B2B leaders — forcing them to rethink their mandate entirely, including how they market, sell, and deliver their offerings to buyers to maximise customer value and drive business growth,” said Dave Frankland, Event Host, Vice President, and Research Director at Forrester. 

Why Traditional GTM Models Are Breaking Down

As the GTM singularity takes hold, the limitations of legacy models are becoming more visible. Built for linear funnels and predictable journeys, these frameworks assume a level of control that no longer exists.

Today’s buyers move fluidly across channels, rely on AI-powered tools to self-educate, and often complete much of their evaluation before ever engaging with a vendor. This behaviour exposes structural weaknesses—rigid planning cycles, fragmented team alignment, and metrics that fail to reflect actual business outcomes.

To remain competitive, organisations must move beyond surface-level optimisation and rethink the underlying operating model that drives GTM execution. To address this shift, Forrester proposes an ARC-based model:

• Augmented: 

As AI agents augment the B2B GTM workforce, leaders will connect AI agents to key B2B GTM initiatives. At the same time, leaders will treat buyer agents as members of the buying network and supply them with relevant content. The goal of this human and machine augmentation must be to amplify value for the customer.

• Resilient: 

Most firms update their GTM plans annually at most. But as buyer behaviour shifts faster and volatility rises, the GTM singularity presents the opportunity to abandon static approaches that no longer serve the company or the customer and instead anchor decisions in customer needs.

• Collaborative:

Sales, marketing, customer success, and product teams still operate in silos. Collaboration necessitates a shared, unified view of the prospect and customer, requiring transparency across teams.

Rethinking Engagement in an AI-Driven Buyer Journey

In an AI-driven landscape, engagement is no longer initiated solely by brands but increasingly mediated by algorithms and intelligent agents. Buyers now interact with content through answer engines, recommendation systems, and autonomous research tools, reducing direct touchpoints with vendors. 

This shift requires organisations to rethink engagement as an always-on, insight-led ecosystem rather than a series of campaigns. Content must be context-aware, dynamically accessible, and tailored not just for human consumption but also for machine interpretation and decision-making.

Forrester outlines the following best practices for B2B leaders to thrive in the GTM singularity era:

• Overcome the visibility vacuum to earn the right to engage. 

When buyers turn to answer engines, they seek information to make confident decisions. As a result, B2B leaders need to design content for humans, buyer agents, and answer engines alike. 

This requires more personalised and ungated information, delivered at scale through sharper segmentation and more nuanced personas.

• Prioritise preference-building to influence decisive buyers.

With purchase and retention decisions hinging on vendor perceptions, building preference early and throughout the buyer journey is critical. This means dismantling the divide between brand and demand and ensuring that the clarity of messaging permeates the full buying network.

• Drive an accountability reset to advance client objectives. 

GTM teams face growing pressure to prove business impact in AI-enabled buying environments. Since most teams still rely on buyer engagement metrics, however, which are no longer an accurate indicator of performance in AI-driven buying, B2B firms should codify a return on objective (ROO) approach that ties metrics more directly to customer goals.

• Calibrate the work of humans and AI to amplify the value of both. 

While AI agents are learning to reason and mimic seasoned B2B GTM professionals, humans will remain GTM’s most valuable asset, even as roles evolve through AI augmentation, cocreation, and simulation. 

To ensure that AI amplifies rather than replaces human impact, onboard AI agents as roles, not tools, and shift focus from automation to outcomes.

The GTM Singularity Demands a Measurable Reset

The research underscores that firms must move beyond legacy KPIs and adopt measurement frameworks tied directly to customer value, business outcomes, and long-term relationships. 

This includes integrating data across functions, aligning incentives to shared objectives, and continuously refining strategies based on real-time insights.

“The impact of the GTM singularity will be seismic, requiring B2B firms to let go of entrenched practices and establish new ways of working. But it is also an opportunity for B2B leaders to rethink how they establish trust and build relationships with their prospects, clients, and beyond,” added Frankland.

In that sense, the singularity is less a disruption to manage and more a reset to embrace, one that rewards organisations capable of aligning intelligence, agility, and collaboration around what matters most: Delivering meaningful value to the customer.
